The Spanish Civil War was a complex conflict with various long-term causes:
- Spain was deeply divided along ideological lines between conservatives and progressives.
- Socioeconomic tensions existed between wealthy landowners and poor peasants.
- Regional nationalism in Catalonia and the Basque Country challenged Spanish unity.
- The monarchy's failures, such as losing colonies to the U.S., weakened its legitimacy.
This ideological and social divide culminated in the 1931 establishment of the Second Spanish Republic and its progressive reforms, which conservative and religious groups opposed, setting the stage for civil war.
